The key induction reaction afforded chiral methyl group moieties using different Evans templates with different configurations. Li_2 Cu Cl_4was effectively employed in the Csp^3 Csp^3 coupling protocol. The target molecular was obtained in a 12.6% overall yield with nine steps in the longest linear route.展开更多
